[BUG] AX - Ordered List Item (ol > li) number announced after element

[alexismandelias]

Describe the bug:

The announcement of the accessibility reader (Android - Talkback / iOS - VoiceOver) is incorrect for <li> elements which are nested in an <ol> element.

Specifically, the number of the list item is announced after the list item content, whereas it should be announced before the list item content.

See more details below in section Expected behavior.

HTML to reproduce the issue:

<ol>
    <li>First list item</li>
    <li>Second list item</li>
    <li>Third list item</li>
</ol>

Html widget configuration:

const html = '<ol><li>First item</li><li>Second item</li><li>Third item</li></ol>';

Column(
  children: [
    const Text('Before'),
    Html(data: html),
    const Text('After'),
  ],
);

Expected behavior:

AX Reader should announce the following, after the user swipes "next" on each Widget:

"Before"
"1. First item. 2. Second item. 3. Second item."
"After"

Actual behavior:

AX Reader announces the following, after the user swipes "next" on each Widget:

"Before"
"First item. 1. Second item. 2. Second item. 3."
"After"
